- This achievement is an equivalent of Garden Crazy in Plants vs. Zombies: Garden Warfare, except that Insanity can also be achieved in Graveyard Ops.
- The image for it shows a close-up of the left half of Crazy Dave's face, with a green spiral in his eye. This is likely because Crazy Dave is crazy, or insane.
- A spiral in an eye is often also used to show insanity in cartoons.
How would you rate Insanity's difficulty?
